Description

GRAPE HOLDER CUP AND CASE OF LIPS PRODUCT

COMPRISING

The present invention relates to a grape-holding cup capable of supporting a grape of solid product, delitable and intended to be slidably mounted in a case, as well as to a product case comprising such a cup. This product grape is, by example, a colored or colorless lipstick stick, or any kind of stick, for example a dermatological stick

Known lipstick sticks are satisfactory as long as the user takes the precaution of storing them so that the tip of the grape, in the storage position, is pointing upwards In practice, for example, when these sticks are stored in a handbag of the user, it is practically impossible to respect this precaution II results, in particular due to shocks and trepidation, that the grapes tend to come out of the cup II should be noted, moreover, that this effect is all the more pronounced, as the grape is subjected to temperature variations Indeed, when certain types of grapes are exposed to a temperature of 30 ° C, the expansion of its diameter can reach 0.6 to 0.7 mm with respect to its normal diameter at room temperature It follows that, following a drop in temperature, a weakening is created at the base of the grape Thus maintaining the grape in a conventional cup is somewhat illusory, because it risks detaching from it, thereafter, at the slightest shock

We know, for example from document FR-A-2 548 880, a lipstick case comprising a cup provided, on the side opposite its bottom, with elastic lugs for attaching the grapes to the undercut. These legs are in abutment against an internal wall of the envelope of the case. This cup, however, has the drawback that, when it slides in the case, its legs undergo vibrations, due to imperfections of this internal wall. from the case. The vibration of the legs then causes a deformation of the base of the grape which is in contact with these legs. Thereafter, the maintenance of the grape in the cup is no longer ensured, and the grape risks detaching from the cup at the slightest shock. Furthermore, the deformation of the base of the grape also occurs when the cup / grape assembly is mounted in the case. This phenomenon is all the more pronounced when the composition of the grape is of a pasty consistency.

In addition, document FR-A-909,021 discloses a lipstick case provided with a cup, the side wall of which has a slot extending over the entire height of the cup. If the presence of this slot improves the sliding qualities of the cup in the case, this slot causes a weakening of the holding of the grape in the cup A first object of the present invention is therefore to propose a cup of stick of lip product which ensures, in all positions of the stick and at variable temperatures, a suitable retention of the grape in its cup.

Another object of the invention is to propose a cup which is simple and inexpensive to make, which also allows easy industrial placement of the grapes in the cup, regardless of the composition of the grapes.

A third goal finally consists in proposing a cup having a diameter 10 greater than that of the grape, which makes it possible to avoid any risk of breakage of the grape at the base, after the mounting of the grape in the cup.

Also, a first object of the invention relates to a grape-holding cup suitable for supporting a grape of solid product which is intended to be mounted.

15 sliding in a case, comprising a substantially cylindrical wall provided with an axis of symmetry and constituting a grape holding skirt, intended to hold the base of the grape, a transverse bottom and means for retaining the grape, at least one opening being formed in the cylindrical wall, this opening extending to the bottom and being delimited by

20 two lateral edges connected by an upper edge opposite the bottom, this opening constituting the grape retaining means This opening also constitutes a means for discharging a surplus of product, moved by the retaining means and / or by the wall internal, when placing the grapes in the cup

27)

The term "substantially cylindrical wall" means any cylindrical wall in the proper sense of the term, or a slightly frustoconical wall on its internal face, flared towards its free edge, opposite the bottom. Furthermore, this free edge can be cut at an angle, depending on the shape of the case intended to contain this cup If necessary, the bottom of the cup can be perforated

Generally, the cup has a circular, oval or prismatic section Most often the cylindrical shape is preferred

J 7)

Advantageously, the cylindrical wall is extended beyond the transverse bottom by a cylindrical guide skirt connected to the bottom in alignment with the cylindrical wall, this skirt ensuring a smooth sliding of the cup when the latter is mounted in a red case. lips

40

According to a particular embodiment of the invention, the opening made in the cylindrical wall is a longitudinal slot of orientation parallel to the axis of the cup II is possible, however to make an opening of rectangular or arcuate shape. circle This opening can, if necessary, also pass through part of the bottom of the cup.

Advantageously, a plurality of openings (or slots) are provided which are distributed regularly over the periphery of the cylindrical wall. openings (or slots) pass through the entire height of the guide skirt defining a plurality of tongues Advantageously, the free ends of the tongues have a diameter slightly greater than the diameter of the cylindrical wall. Thus, these tongues can carry, for example, an external boss. centering In this way, the tongues permanently ensure flexible contact with the wall of a sheath of the case, guaranteeing a smooth sliding and without play of the cup in the case, playing the role of shock absorber In particular, during during assembly, during transport or when handling a lip case, this damping effect reduces or avoids the risk of breakage of the base of the grape

Due to the arrangement of the slots and the tongues respectively, which has just been described, the cylindrical wall, on the side opposite the bottom, has a continuous edge

Advantageously, each orifice (or slit) is associated with an anchoring means, capable of entering the base of the grape

According to a first alternative embodiment, each orifice (or slot) practiced in the cylindrical wall is surrounded by an extra thickness called

Advantageously, each gadroon has a rounded edge in the vicinity of the internal wall of the retaining skirt. On the side of the slot, the gadroon forms an angle of substantially 90 ° with the internal cylindrical wall. Advantageously, the excess thickness of each gadroon is of the order of 0, 1 to 5 mm By the arrangement of these gadroons, it is possible to further strengthen the retention of the grapes in the cup. In a junction zone with the cylindrical wall, the gadroons have a rounded edge facilitating the placing in industrial place of the grape in the cup This placement of the grape is carried out, advantageously, at a temperature below ambient temperature, for example at 10 ° C. at this temperature, the grape has a diameter less than a few 0 ^th of millimeters of the diameter it presents at room temperature, and a few 10 ^th of a mm less than the internal diameter of the cup When returning to room temperature, the r aisin expands and remains “anchored” in the slots and / or gadroons During this expansion, part of the material of the grape moves and penetrates into the orifices, thus ensuring the retention of the grape in the cup The grape, placed in thus placed in the cup, is much better resistant to falls and tremors than a grape placed in a conventional cup, both at high temperatures and cold

According to another variant, it is also possible to have a godron of suitable shape between the slots

According to another alternative embodiment, the anchoring means is an elastically flexible piece, capable of bending radially outward, during the positioning, of the grapes and of sinking into the base of the latter. this part is located to the right of an orifice, on the internal surface of the side wall of the cup or in the thickness thereof part can be in the form of a fin, for example of triangular or trapezoidal shape, part of one of the sides of the fin being attached to the internal face of the cylindrical wall, this fin being oriented along a plane passing through the axis of the cup Advantageously, the shape of the fin is chosen to facilitate the introduction of the base of the grape into the cup

In general, the gadroons or the fins can be arranged on a variable height of the internal lateral wall of the cup.

Where appropriate, the cup has two projecting studs on the outside, these studs being intended to control the movement of the cup, when it is mounted in a case.

A second object of the present invention relates to a case for a lip product comprising a grape, the base of which is engaged in a cup as described above. This cup is of the type with two nipples projecting radially outwards and which, ^{on the} one hand, each pass through a light, these lights being formed in the side wall of a sheath in which the cup moves substantially in the axial direction, and on the other hand, each engage in a helical groove formed in the inner wall of a cylindrical jacket externally lined with an envelope, the sheath being mounted movable in rotation relative to the envelope and retained axially. The axial distance, separating the pins from the edge of the cup on the one hand, and the axial position of the ends of the slots and / or grooves respectively on the sleeve and / or the shirt on the other hand, is such that, when the grape is in its maximum outward position, the edge of the cup is not out of the sheath

To better understand the present invention, we will now describe, by way of purely illustrative and in no way limitative, several embodiments of cups according to the invention, shown in the accompanying drawings.

Referring to Figures 1 to 3, there is shown a case of lip product having a longitudinal axis X, comprising an outer protective casing 1, for example metallic, of cylindrical shape, of circular section, one edge of which is collared rounded 2 towards the axis X II delimits a central circular passage 3 Inside the envelope 1, is fixed a cylindrical jacket 4 of circular section, of small thickness, made of plastic material It has a height smaller than the envelope 1, so as to form, on the side of the collar 2, an annular chamber 5, delimited by this collar and by a first end 4a of the jacket 4 On the side opposite to the collar 2, an annular recess 6 is delimited between the envelope 1 and a second end 4b of the jacket 4. In the internal face of the jacket 4, two helical grooves 7 are formed, identical but diametrically opposite

In the assembly constituted by the envelope 1 and the jacket 4 is mounted a sheath 8, made of rigid plastic material, free to rotate around the axis X, but fixed in the axial position. The sheath 8 comprises a tubular cylindrical middle part 9, of external diameter slightly less than the internal diameter of the jacket 4 At its ends, this sheath comprises respectively a retaining cord 10 and a maneuvering tip 15

Two identical longitudinal holes 1 1, diametrically opposite, extend axially over practically the entire height of the tubular part

9 Each light has two ends which end respectively with a lateral notch 12 and 13 With respect to the light 1 1, the notch 12 located at a first end of a light 1 1 is oriented opposite to the notch 13 located on the second end of the light 1 1

At its end, opposite the recess 6, the tubular part 9 is connected via an external radial shoulder 14 to a cylindrical operating nozzle 15, the internal diameter of which is equal to the internal diameter of the tubular part 9, and whose external diameter is practically equal to the diameter of the casing 1 At its free end, the end piece 15 has an internal radial collar 16

When the tubular part 9 is disposed in the jacket 4, the annular retaining cord 10 (FIG. 1) abuts against the end 4b of the jacket 4, and is engaged in the chamber 5, ensuring the axial maintenance of the sheath in the jacket 4 Similarly, the external radial shoulder 14 is housed in the annular recess 6, so that the jacket 4 is sandwiched axially between the cord 10 and the shoulder 14 Thus, the sleeve can be rotated in the folder 4 by operating the operating tip 15

According to the invention, a cup 30, of generally cylindrical shape, is mounted in the sheath 8. This cup 30 has a cylindrical wall 20 and a cylindrical guide skirt 21, separated from each other by a bottom 22. The cylindrical wall 20 has on its outer side wall two studs 24 projecting outwards Each stud has a dimension such that it can pass through a lumen 11 of the sheath 8 and be engaged in a groove 7 of the jacket 4

In the wall of the cylindrical wall 20 are formed, substantially at mid-point, longitudinal slots 29 parallel to the axis X, opening towards the bottom 22 and crossing the entire height of the wall of the guide skirt 21 Thus, a plurality of elongated openings 29a are defined in the cylindrical wall 20, serving as an anchoring means, during the placement of the grape 40

As for the guide skirt 21, the slots 29 define tongues 23

Thanks to the material constituting the cup 30, for example polyacetal, polystyrene or polypropylene, these tongues 23 have sufficient elasticity to guide the cup, flexibly, during its axial stroke in the sheath 8 Advantageously, bosses 21 a are provided on the external face of each tongue 23, intended to eliminate any play between the cup 29 and the sheath 8

It is understood that, when the sheath is rotated relative to the jacket 4 and the casing 1 around its longitudinal axis X, thanks to the guidance of the pins 24 in the slots 1 1 and the grooves 7, the cup 30 moves axially in the tubular part 9 of the sheath 8 The rotanon of the sheath Drovoque an axial translation of the cup in the helical grooves 7 of the liner 4 between two extreme positions, one of which is the retracted position of the grape, shown in FIG. 1 In this retracted position of the cup 30, the guide skirt 21 is housed inside the end piece 15, in the vicinity of the internal collar 16

Figures 4 to 6 illustrate an alternative embodiment of the cup of Figure 3 The constituent parts of this cup which are identical to those of Figure 3 or play a similar role, have the same reference numbers increased by 100 The description of these parts will only be partially taken over

Similarly to the embodiment of FIG. 3, the cup 130 of FIG. 4 has a substantially cylindrical shape. The cylindrical wall 120 and the guide skirt 121 have slots 129 which open substantially from the mid-height of the cylindrical wall. 120 to the free end 121 b of the skirt of i7> guide 121 Thus, a plurality of elongated slots 129a are formed in the lower part of the cylindrical wall 120 Each slot 129a, on the internal face of the cylindrical wall 120, is surrounded by a reinforcement zone or "godron" in excess thickness 150 This excess thickness 150 is of the order of 0.6 mm The outer edge 151 of the excess thickness 150 is 0 rounded to facilitate the placement of the grapes in the cup 130, as visible in Figure 5 which shows a cross section along the plane P of Figure 4

From the side of the slot 129 the light 129a forms with the cylindrical wall a τ _> sharp angle γ, substantially equal to 90 °, as shown in Figure 6

The gadroons 150 form an excellent means of anchoring for a grape of semi-solid consistency, ensuring the maintenance of the grape, in particular at high temperatures, around 30 °

30

Figures 7 to 9 illustrate another variant of cup 230 The constituent parts of this cup which are identical to those of Figure 3 or play a similar role, have the same reference numbers increased by 200 The description of these parts will not be repeated that 3τ> partially

The cup 230 is distinguished from the cup 30 of FIG. 1 by the fact that the cylindrical wall 220 includes a plurality of internal hooking fins 250 These fins 250 have a triangular, rectangular shape and

40 extend radially towards the interior of the cup They are attached to the cylindrical wall 220 at a level situated above the apex 251 of each slot 229, so that an acute angle α is defined between the skirt 220 and the hypotenuse of the triangle Typically, the angle α is between 20 ° and 45 ° On only part of its length, the side adjoining I angle α is

45 integral with the cylindrical wall 220 This construction makes it possible to obtain an elastically mobile arrangement of the fins 250 It is understood that, during the mounting of the grape in the cup, the fins 250 can flex radially outwardly in the space left by the slots 229 After the implementation place of the grape, the fins enter the base of the grape by elasticity, ensuring the maintenance and anchoring of the latter in the cup

As for the bottom 222, in the extension of each slot 229, notches 260 have been provided in the bottom 222, these notches serving to remove the molding pins forming the slots 229 and the base 252 of the fins 250

FIG. 10 shows another arrangement of the grape hooking means. In FIG. 10, the upper edge of the opening 329 which is formed in the side wall 320 carries a tongue 350. This tongue is radially flexible. It is directed towards the bottom 322 of the cup and oriented, at an obtuse angle α, towards its interior The free end 352 of the tongue carries an anchoring point. During the introduction of the grape into the cup, the tongue 350 flexes outward, and then gradually enters the mass of the grape, thanks to the pasty consistency of the latter The anchor point 352 increases further maintaining the grape and preventing any accidental exit of the grape The product displaced during this operation can then go to the opening 329

Figures 1 1 to 13 illustrate a preferred embodiment of the invention, showing a lipstick case The constituent parts of this cup which are identical to those of Figure 1 or play a similar role, have the same numbers reference increased by 400. The description of these parts will only be repeated partially

The case 400 of FIG. 11 has a cylindrical base 415 with closed bottom 416 into which a cylindrical sleeve 408 is forced into place. The lower part of this sleeve is surrounded by three gadroons in the form of a portion of washer 415a, 415b, 415c , thin, extending radially outwards These washer portions are discontinuous to increase their flexibility in the axial direction of the sleeve, which facilitates the mounting of the mechanism In the cylindrical side wall 409 of the sleeve 408 two slots are made 41 1 located opposite and axially oriented In these slots are arranged the two pins 424 of the cup 430

The cup 430 has substantially the same construction as that shown in Figure 10

As can be seen, in particular in FIG. 12, the sheath has a shoulder 414, in the vicinity of which an O-ring 414a is made, made of elastomeric material. The external periphery of this seal 414a is in contact, with gentle friction, against the lower part. internal of a metallic cylindrical casing 401 In the upper part of the metallic casing 401 is mounted a cylindrical jacket 404, the internal wall of which is provided with two internal grooves, intended to receive the pins 424 of the cup 430 (see also figure 13 ) In the cup 430 is mounted a grape of lipstick 440 To protect the grapes, this assembly is closed by a cylindrical cap 460 at the bottom of which is disposed a block of cellular foam 401 a whose face facing the grape is covered with a flexible and waterproof film 401 b This block of foam prevents accidental release of the 440 grape during transport and also ensures the tightness of the case, in order to reduce, if necessary, the drying of the grape

FIG. 13 shows the arrangement of the grapes 440 in the cup 430 When the grapes are introduced into the cup, the tongues 450, arranged at the top of the openings 429, create in the base of the grapes traces 431 oriented axially To increase the resistance of the grapes in the cup, the grapes are rotated in the direction of the arrow F, for example by an angle of 10 ° or 20 ° By this operation, the lines get an angled shape 432 The product displaced during this operation can escape through openings 429 and help maintain the grape

In all the embodiments, the placement of the grape in the cup is easy, because, when there is a compression, during this operation, of the base of the grape, in particular by the fins 250, the tongues

350, 450 or the gadroons 150, any excess product can escape through the slots 29, 129, 229 of the cup 30, 130, 230, and thus contributes to the anchoring of the base of the grape in the cup. The cup of figure 3 is studied for the fixing of a grape of relatively hard consistency, while the cup of figures 4, 7, 10 and 13 can be used to support and maintain a grape of semi-solid consistency

The invention is also particularly advantageous in that it allows, because of the new grape mounting system, to have a grape whose diameter is very close to the diameter of the cup. This makes it possible to prevent the grape is mounted askew in the cup Thanks to the presence of the slots, the surplus product, displaced at the base of the grape during the establishment of the latter, by the internal wall of the cup and possibly by the gadroons, can be evacuated through the slots In addition, the invention applies equally to conventional lipstick mechanisms as to lip pens which have a more slender shape than conventional mechanisms In this case, the cup does not have lugs on the external side wall, but is integral with a screw extending axially from the bottom of the cup II It is understood that such a pen can be used for the distribution of any other table product, capable of being fi attached in a cup, such as a kohl pencil for eye makeup, or makeup chalk
